The trouble in Latin America and the Caribbean (including some of the places I have heard plasma tech pitched), as in much of the developing countries, there are no tipping fees. In fact, there usually are no landfills, just dumps, usually open-air, with little to no management. So we?d be talking government subsidies, usually from governments that can ill afford to subsidize basic health care, let alone waste management. Furthermore, unless someone is pre-sorting (who? And who pays them to? How paid? Under what conditions?), then the wastes going from one of these dumps (say, for the sake of argument, Duquesa in Santo Domingo, one of the places this idea was pitched for), WILL have metal (unlike glass, not heavily recycled in the DR), old automobile batteries, car hulks, end-of-life electronics, spent portable batteries, infectious medical wastes (even limbs), pesticides, you name it, it?s all thrown in the dump (if not in the river). What made me suspicious about these pitches is that they supposedly solved all problems, at no cost to government or the general public, and no close environmental supervision necessary. In my experience, nothing is free and even cheap wonder techs have their trade-offs. It?s just a question of discussing the trade-offs fully and openly and weighing the balance of costs and benefits and deciding priorities. But so far the proponents of this tech I have heard speak and questioned never seem to remember a trade-off to speak of. Makes one stroke his/her chin in thought and go ?hmmmm?? As I said, it may be all it?s purported to be. But I still must wonder why, if it is so beneficial and so cheap, are most of the full-scale projects (beyond pilot and test phases) announced in China and developing countries like Panama? Why not California? Massachusetts? New York? Michigan? Germany? The UK? The Netherlands? Japan? What?s wrong with this picture? What else are we not being told? ----------------------------------------------- Sr. Keith Edward Ripley Temas Actuales LLC telefono: 703-731-7108 e-mail: keith.ripley@no.address <http://www.temasactuales.com/> http://www.temasactuales.com <http://www.dr1.com/blogs/?u=environment> El Equipo Verde Autor del libro "Solid Wastes and Recycling Policy in Latin America & the Caribbean" <http://www.temasactuales.com/temas_in_print/index_wastebookpromo.php> http://www.temasactuales.com/temas_in_print/index_wastebookpromo.php Noticias ambientales de América Latina y el Caribe: <http://www.temasactuales.com/whats_new/index.php?page=1> http://www.temasactuales.com/whats_new/index.php?page=1 Las leyes/los reglamentos ambientales de todo America Latina y el Caribe: <http://www.temasactuales.com/laws_policies/LawDbase.php> http://www.temasactuales.com/laws_policies/LawDbase.php Perspectivas sobre la evolucion de politica sobre el medio ambiente, salud publica y defensa del consumidor en America Latina y el Caribe: http://www.temasactuales.com/temasblog Este mensaje es solo para el uso del Destinatario y puede contener información que ES CONFIDENCIAL.

The money comes from tipping charges or government subsidy. Plasma 4th state of matter is a really interesting thing. Using available technology since 1950's such as Westinghouse Plasma the working area of a torch is about 16 inches MAX . You need lots of torches and lots of power to break down waste to gas and elements this way. About 1/2 of the Syn gas produced is consumed to power up the system. No electical power no plasma no work. I compare it to Edision the light bulb and DC power. Works not well on the large scale. Using low volatge with a heatsink as on electrical contact totally different outcome. Heat of the heatsink sustains the decomposition. Each heatsink adds working area of 16 in approx 8 heatsinks x 16" all in a box 5' 6' 3' approx. Really efficient and clean! Anyone who puts any metal in a plasma field for recycle is at minimum an idiot you get nothing out for the trouble. You put recycles with H and C compositions such as garbage, manure, ag waste, plastics, auto fluff, old carpets, paper, cardboard and the like and you get process heat, gasses rich in C and H and a mini RE refinery. No process I have heard about comes even close in energy effciency or minimizes greenhouse gases and water use. And it is really cheap too.
